Long-Range Canon DSLR Video Trigger (V2, greatly simplified)

This is a re-visit of my first Instructable (found here: http://www.instructables.com/id/Remote-Canon-DSLR-Video-Trigger/).   That version worked just fine, but was a bit expensive, a bit big and heavy, and certainly way more complicated than it needed to be.   It did have some nice features, like a beep to start recording, and a blinking light to indicate recording had been triggered, but overall, that was the "Bringing a gun to a knife fight" approach.   

This is a much simpler, cheaper, quicker and easier to build version that does the same thing: Triggers the video recording function on a Canon DSLR from a long distance (ie. well beyond 3-5 meter (12-16ft) range of an IR remote).   This hack enables you to trigger your DSLR video record function from at least 150ft, possibly up to 300ft (depending on how capable your remote is).  

When is this useful?  Solo filming (Survivorman-style), having your camera at the end of a jib arm, in a tree, strapped to the outside of a car, or any other inconvenient-to-push-record-button location.  

A simple IR remote works fine if you are in front of the camera and close enough for the camera to pick up the IR from the remote.   

How this hack works: 
The receiver of the wireless RF trigger is connected to the IR remote to act like the "2S" button.  When the button on the RF remote transmitter is pressed, the IR remote acts like the 2S button has been pushed, which sends an IR signal your Canon DSLR to start recording video.  (Of course, you have to have the IR remote pointed at the IR receiver on your DSLR for this to work).

Step 1 What you need.

Let's get started!  Here is what you are going to need:

Parts: 
- Wireless RF Shutter Release for Canon - I am using one sold as "Alzo Wireless Radio Shutter Release" on Amazon.  Make sure it has the 2.5mm plug - $20 - 30
- IR remote for Canon camera - Canon RC-1 compatible, it needs to have the "2S" option, which is what triggers the video when the camera is in video mode.   I am using a "Shoot" branded one, again bought from Amazon (also available on Ebay for cheap) - $3 - 4 
- 2.5mm (3/32") stereo female jack - I got mine at Vetco.net, but RadioShack should have them too.  - $0.99
- Small bit of wire (24-gauge, or something else pretty thin)
- Velcro with a self-adhesive backing - $3

Total Cost: < $40

Tools:
- Soldering iron
- Wire strippers
- Miniature Phillips head screwdriver
- Dremel tool or drill
- Multi-meter (helpful but not absolutely necessary)
- Hot glue gun (again, not necessary, but handy for increasing the durability)
